Description
Gebiet der ErfindungField of the invention
Die Erfindung betrifft ein Vierpunktlager nach den oberbegriffsbildenden Merkmalen der beiden unabhängigen Patentansprüche 1 und 7.The The invention relates to a four-point bearing according to the preamble forming Characteristics of the two independent ones claims 1 and 7.
Hintergrund der ErfindungBackground of the invention
Vierpunktlager haben am Innen- und am Außenring je zwei kreisbogenförmige Laufbahnen, deren Krümmungsmittelpunkte so gegeneinander versetzt sind, dass die Lagerkugeln die Laufringe bei radialer Belastung in vier Punkten berühren. Einer der beiden Laufringe, meistens der Innenring, ist geteilt ausgeführt, damit die Lagerkugel eingeführt werden können. Vierpunktlager sind für wechselnde, rein axiale Belastungen oder überwiegende Axiallast geeignet. Dabei berühren die Lagerkugeln den Innen- und den Außenring nur an je einem Punkt, wie in einem axialbelasteten einreihigen Schrägkugellager. Die Druck winkel der Vierpunktlager sind gewöhnlich groß. Es kann daher hohe axiale Kräfte in beiden Richtungen aufnehmen. Hauptanwendungsgebiet ist der Getriebebau, wo axiale Belastungen in beiden Richtungen auftreten und wo eine enge axiale Führung und eine geringe Lagerbreite gefordert werden.Four point contact bearings have on the inner and outer ring two circular arc-shaped each Raceways whose centers of curvature are offset from each other so that the bearing balls the races touch at four points in case of radial load. One of the two races, usually the inner ring is split, so that the bearing ball can be inserted. Four point contact bearings are for changing, purely axial loads or predominantly axial load suitable. Touch it the bearing balls the inner and the outer ring only at one point, as in an axially loaded single row angular contact ball bearing. The pressure angle the four-point bearings are usually large. It can therefore high axial forces record in both directions. Main field of application is gearbox construction, where axial loads occur in both directions and where one tight axial guidance and a small bearing width are required.
Ein
derartiges Vierpunktlager ist beispielsweise aus der
Nachteilig dabei ist, dass durch den verwendeten im Käfig in Umfangsrichtung weniger Lagerkugeln unterbringbar sind, so dass die Tragfähigkeit eingeschränkt ist. Ein weiterer Nachteil ist dadurch begründet, dass die Breite der Lagerkugeln nur etwa zur 70% genutzt wird, so dass axialer Bauraum verschwendet und das Gewicht erhöht wird.adversely it is that less by the used in the cage in the circumferential direction Bearing balls are accommodated so that the load capacity is limited. Another disadvantage is due to the fact that the width of the bearing balls only about 70% is used, so wastes the axial space and the weight increases becomes.
Zusammenfassung der ErfindungSummary of the invention
Ausgehend von den dargelegten Nachteilen des bekannten Standes der Technik liegt der Erfindung daher die Aufgabe zugrunde, eine Vierpunktlager bereit zu stellen, das die vorstehend beschriebenen Nachteile nicht aufweist.outgoing from the stated disadvantages of the known prior art the invention therefore has the object of a four-point bearing to provide that does not have the disadvantages described above having.
Erfindungsgemäß wird diese Aufgabe nach dem kennzeichnenden Teil von Anspruch 1 in Verbindung mit dessen Oberbegriff dadurch gelöst, dass die Wälzkörper als Kugelrollen mit jeweils zwei symmetrisch von einer Kugelgrundform abgeflachten, sowie parallel zueinander angeordneten Seitenflächen ausgebildet und vollrollig angeordnet sind.According to the invention this Task according to the characterizing part of claim 1 in conjunction solved with the preamble by the fact that the rolling elements as Ball rollers each with two symmetrical from a ball basic shape flattened, as well as mutually parallel side surfaces formed and are arranged full complement.
Gegenüber einem Vierpunktlager nach dem bisherigen Stand der Technik ergeben sich durch das Abspecken der schlanken Kugelrolle gegenüber bekannten Lagerkugeln nachstehend aufgeführte Vorteilsvarianten für:
- – leistungsfähiger, aber axial schmäler bei gleichen Außendurchmesser
- – leistungsfähiger bei gleicher Breite, aber mehr Fettraum
- – leistungsgleich, aber radial kleiner und axial schmäler
- - more efficient, but axially narrower with the same outer diameter
- - more efficient with the same width, but more fat space
- - equal power, but radially smaller and axially narrower
Weitere vorteilhafte Ausführungsvarianten des erfindungsgemäßen Vierpunktlager sind in den nachstehenden Unteransprüchen 2 bis 6 beschrieben.Further advantageous embodiments of the four-point bearing according to the invention are described in the dependent claims 2 to 6 below.
So geht aus Anspruch 2 hervor, dass der Lageraußenring zweiteilig ausgebildet ist und in einen rillenförmigen Laufbahnfreistich Abstandstrennkugel angeordnet sind. Die Trennung des Lageraußenringes hat den Vorteil, dass bei einer schnellen drehenden Welle durch die fehlende Zweiteilung des Lagerinnenringes keine Einbußen der Laufbahnqualitäten hingenommen werden müssen. Die im rillenförmigen Laufbahnfreistich des Lageraußenringes angeordneten Abstandstrennkugeln sorgen dafür, dass die Kugelrollen sich bei Betrieb des Lager nicht an ihren Umfangsflächen gleitend berühren, so dass die Reibung vermindert ist. Außerdem sorgen die Abstandtrennkugel dafür, dass ein leiserer Lauf der Lagereinheit gewährleistet ist.So goes from claim 2 shows that the bearing outer ring formed in two parts is and in a groove-shaped Laufbahnfreistich distance separating ball are arranged. The separation of the bearing outer ring has the advantage that when a fast rotating shaft through the lack of division of the bearing inner ring no losses of Career qualities accepted Need to become. The grooves in the groove-shaped track of the bearing outer ring arranged spacer balls ensure that the ball rollers themselves during operation of the bearing do not slide on their peripheral surfaces, so that the friction is reduced. In addition, the distance separating ball provide for this, that a quieter running of the storage unit is guaranteed.
Nach einem zusätzlichen Merkmal der Erfindung sind die Abstandstrennkugel gemäß Anspruch 3 aus einem Kunststoff oder einer Keramik gefertigt.To an additional Feature of the invention are the distance separating ball according to claim 3 made of a plastic or a ceramic.
Nach einem anderen Merkmal gemäß Anspruch 4 soll einer der Lagerringe mit je einer Deckscheibe drehfest verbunden sein, deren anderes radiales Ende vom zugehörigen anderen Lagerring durch einen Spalt beabstandet ist.To another feature according to claim 4 is one of the bearing rings rotatably connected, each with a cover plate be, the other radial end of the associated other bearing ring through a gap is spaced.
Als vorteilhaft hat es sich in diesen Zusammenhang erwiesen, wenn gemäß Anspruch 5 die Deckscheiben aus einem Eisenwerkstoff gefertigt sind, der einem Härtevorgang unterworfen ist. Der Nutzen der vorhandenen Deckscheiben ist zweifach zu bewerten. Zu einem sorgen sie dafür, dass das Lager ordnungsgemäß abgedichtet ist, so dass im Lager vorhandenes Schmierfett nicht nach außen dringen kann und Schmutz von außen nicht in das Innere des Lagers gelangen kann. Zum anderen können sich die Kugelrollen stirnseitig an den Dichtscheiben vorteilhaft abstützten, denn bei kleinen Drehzahlen und geringen Radialkräften neigen diese zum seitlichen Verkippen.When Advantageously, it has proved in this context, if according to claim 5 the cover plates are made of a ferrous material, the a hardening process is subject. The benefit of existing shields is twofold too rate. At one thing, they make sure the bearing is properly sealed is so that in the camp existing grease does not escape to the outside can and dirt from the outside can not get inside the warehouse. For another, you can the ball rollers frontally supported advantageously on the sealing discs, because at low speeds and low radial forces, these tend to be lateral Tilting.
Nach einem weiteren Merkmal der Erfindung ist nach Anspruch 6 vorgesehen, dass der zweiteilig ausgebildete Lagerring an mehreren voneinander beabstandet Umfangsstellen mit je einer Ausnehmung versehen ist, in die ein zugehöriges Halteelement eingesetzt ist. Auf diese Weise ist eine formschlüssige Verbindung zwischen den beiden Lagerteilringen gebildet, so dass sich diese bei Transport nicht voneinander trennen können.To a further feature of the invention is provided according to claim 6, that the two-part bearing ring at a plurality of spaced apart Circumferential is provided with a respective recess in the one associated Retaining element is inserted. In this way is a positive connection formed between the two bearing part rings, so that this can not be separated during transport.
Die Aufgabe der Erfindung wird nach dem kennzeichnenden Teil des zweiten unhabhängigen Anspruchs 7 in Verbindung mit diesem Oberbegriff auch dadurch gelöst, dass die Wälzkörper als Kugelrollen mit jeweils zwei symmetrisch vor einer Kugelgrundform abgeflachten, sowie parallel zueinander angeordneten Seitenflächen ausgebildet und vollrollig angeordnet sind und der Lageraußenring mit einen durchgehenden Axialschlitz versehen ist.The The object of the invention is according to the characterizing part of the second independent claim 7 in connection with this preamble also solved in that the rolling elements as Ball rollers each with two symmetrical in front of a ball basic shape flattened, as well as mutually parallel side surfaces formed and full complement are arranged and the bearing outer ring with a continuous Axial slot is provided.
Der Vorteil dieser zweiten Ausführungsvariante des erfindungsgemäßen Vierpunktlagers liegt insbesondere darin, dass aufgrund des fehlenden Sprengens eines der Lagerringe dieser sich nicht in der Rundheit nicht verändert, was sich positiv auf die Qualität der Laufbahn auswirkt. Ansonsten gelten die gleichen Vorteile wie unter der ersten Erfindungsvariante bereits ausgeführt.Of the Advantage of this second embodiment of the four-point bearing according to the invention lies in the fact that due to the lack of blasting one of the bearing rings of this does not change in the roundness, what positively to the quality the career path. Otherwise, the same benefits apply as already executed under the first variant of the invention.
In vorteilhafter Weiterbildung dieser zweiten Erfindungsvariante ist nach Anspruch 8 vorgesehen, dass einer der Lagerringe mit je einer Deckscheibe drehfest verbunden ist, deren anderes radiales Ende vom zugehörigen anderen Lagerring durch einen Spalt beabstandet angeordnet ist.In Advantageous development of this second variant of the invention is provided according to claim 8, that one of the bearing rings, each with a Cover disc is rotatably connected, the other radial end of associated another bearing ring is arranged spaced apart by a gap.
Schließlich sollen ach einem letzten Merkmal der Erfindung nach Anspruch 9 die Deckscheiben aus einem Eisenwerkstoff gefertigt und einem Härtevorgang unterworfen sein.Finally, should After a last feature of the invention according to claim 9, the shields made of a ferrous material and subjected to a hardening process.
Auch hier gelten die bereits aufgeführten Vorteile analog zur ersten Erfindungsvariante.Also Here are the benefits already listed analogous to the first variant of the invention.
